While not necessarily so limited the invention is well adapted to be embodied in a fused switch, and particularly in a switch of this type adapted for a plug fuse. The fused switch shown in Figs.' 1 to 6 will rst be described.

'I'here is a main insulating base I upon which most of the other electrical parts of the appliance are supported. The base I has a side face Ia perpendicular to the rear face thereof. Directly associated with the base is a metallic plate 2 having a portion 2 at the rear of the base and connected therewith and having a side portion 2b adjacent the side face IEL of the base and spaced therefrom. The plate 2 may be directly connected with the base i by means of hollow eyelets or tubes 3, 3 as clearly shown in Fig. 3 although such direct connection may be omitted if desired. Preferably the plate 2 is provided with a' sheet or lining 4 of insulating material which is interposed between the said plate and the base and which also extends along the portion 2'L at the inner side thereof as shown.

The base l and the metal plate 2 are both connected with a suitable rear support by means of screws 5, 5, and when eyelets such as 3, 3 are provided the screws 5, 5 may extend through them. The rear supporting wall may be and preferably is the rear wall of an enclosing box such as 6, the box having an openable front cover 5 hinged at one side. Preferably the side portion 2h of the plate 2 is immediately adjacent theside wall of the box as shown in Fig. 5.

A flat insulating plate such as 1 is positioned between the side face In of the base and the side portion 2b of the metal plate and is manually movable in parallelism therewith. I do not limit myself as to the character of the movement of the plate 1, but in the appliance shown in Figs. 1 to 6 the movement is pivotal about a suitable bearing member 8 carried by the side portion 2b of the metal plate. This bearing member is in the form of a shouldered pin which may be formed of insulating material and which extends into a hole in the plate 2. The outer end of the bearing pin 3 may be upset to hold it in place and the side wall of the box may be provided with a suitable clearance opening as shown at 9.

Two stationary switch contacts III and I I are mounted on the base I, being respectively located adjacent the inner and outer surfaces of the movable insulating plate 1. The inner contact I0 is connected with a wire terminal I2 on' the base. The outer switch contact has a lateral extension II* which extends across or bridges the planes of movement of the insulating plate 1 and is held in place on the base by a screw I3. The plate 'I is provided with a notch I4 to avoid interference between the said plate and the bridging extension Il. The extension II is provided with a wire terminal I5 positioned close to the side face I of the base.

Carried by the movable insulating plate 1 is a conducting element |6 which extends through a suitable aperture in the said plate. 'I'his element is so positioned that upon pivotal movement of the plate 1 it is moved into or out of a position between the stationary contacts I3 and II. Figs. 3 and 5 show the element I6 in its closed-circuit position between the contacts,and Fig. 4 shows it in its open-circuit position out of engagement with the contacts. f

In order that the plate 1 may be manually moved, it is provided with an extension 1B which constitutes a handle, this handle portion projecting through a slot I1 in the front cover of the box. It will be seen that by moving the handle 18L upward or downward the plate 1 with the contact I6 thereon can be moved to close or open the circuit as desired. The slot I1 is wider than the projecting portion of the plate 1 in order that there may be no interference when the cover is opened. In order that the unoccupied portion of the slot I1 may be normally closed the plate 2 is formed with an inward extending flange 2.

As already stated, the invention is particularly applicable to a fused switch, and when fuse contacts are provided they are mounted on the base so as to be accessible from the front thereof. Plug fuse contacts I8 and I9 are shown, these being mounted in a recess in the base and being close to the side wall la of the base. The screw constituting the center contact |8 is connected directly with a lateral extension lformed integrally with the stationary switch contact III, and the shell contact I9 is connected with the wire terminal I2 by means of a conductor I9 of conventional type. If desired the base I may be provided with a terminal 20 adapted for the connection of neutral wires.

The construction shown in Figs. '7 to 11 is in many respects similar to that already described. The main insulating base is shown at 2|, and associated with this base is a metal plate 22 having a rear portion 22 and a side portion 22h. ,An insulating liner 23 is provided for the plate 22. The base is connected with the rear portion of the plate by means of eyelets or tubes 24, 24. The enclosing box 25 with its side hinged cover 26 is similar to the box already described, and the base 2| and the plate 22 are secured to the rear wall of the box by means of screws 21, 21.

The iiat insulating plate 28 is positioned between the side face 2|al of the base and the side portion 22b of the metal plate, but is adapted to move rectilinearly instead of pivotally. It is guided at the rear by the insulating Sheet 23 which is supported by the rear portion 22B of the metal plate and at the front it extends through a slot 29 formed in an inward projecting ange 22c on the metal plate.

Two stationary switch contacts 30 and 3| are mounted on the base 2|, being respectively located adjacent the inner and outer surfaces of the plate 28. The inner switch contact is connected with a wire terminal 32, preferably through fuse contacts 33 and 34 in the manner already described. The outer switch contact 3| has a lateral extension 3 Il which-extends across or bridges the planes of movement of the insulating plate 28 and is held in place on the base by a screw 3 Ib. The plate 28 is provided with a notch 28h to avoid interference between the said plate and the bridging extension 3I. The extension 3|is provided with a wire terminal 35 positioned -close to the side face 2| of the base. If desired the base 2| may be provided with a terminal 36 adapted for the connection of neutral wires.

Carried by the movable insulating plate 28 is a conducting element 31 which extends through a suitable aperture in the said plate. This element is so positioned thaty upon rectilinear movement of the plate 28 it is moved into or out of a position between the stationary contacts 30 and 3|.

A Figs. 9 and 11 show the element 31 in its closedcircuit position between the contacts, and Fig. 10 shows it in its open-circuit position out of engagement with the contacts.

In order that the plate 28 may be manually moved it is provided with an extension 28* which constitutes a handle, this handle portion projecting not only through the slot 29 in the flange 22e, but also through a slot 38 in the front cover 26 of the box. The slot 38 is wider than the projecting portion of the plate 28 in order that there may be no interference when the cover is opened. It will be observed that the inward extending flange 22 serves to normally close the right hand portion of the slot.

It has already been stated that the plate 28 is guided at the rear by the insulating sheet 23. In order that it may be properly guided at the front there is provided a long narrow metal plate 39 having an opening therein through which the handle 28i projects. This plate 39 moves with the plate 28 and engages the inner surface of the flange 22, thus serving to guide the plate 28 at the front and to prevent forward movement thereof.

The plate 39 serves the further purpose of closing that portion of the slot 38 which is not occupied by the handle 28.

Preferably in order that the switch member, that is, the plate 28 with `the contact 31 thereon, may be moved with an approximation of a snap action, the plate 39 is preferably resilient so as to serve as a detent member adapted to momentarily resist movement of the switch member in either direction. Preferably and as shown the iiange 22= is bent inward to provide two V-shaped projections 40 and 4| and the resilient plate 39 is similarly bent to form V-shaped recesses 42 and 43. With the parts in the position shown in Fig. 9 the projection 48 is engaged in the recess 42 and these parts resist any pressure exerted to move the switch member downward to open the circuit. When the pressure is increased sufiiciently to overcome the resistance offered at 40, 42 the switch member will move quickly downward with the approximation of a snap action. Similarly, when the switch member is in its lower open-circuit position, the projection 4| is engaged in the recess 43 and these parts resist any pressure exerted to move the As shown in Figs. 11 and 12 the rear portion 22a of the plate 22 is formed with a slot 44 of such size and shape as to be adapted to receive the switching member for purposes of assembly. In the completed appliance, however, the slot 44 is closed by the insulating sheet 23 and also by the base 2|. During assembly the switch membei is inserted from the rear through the slot 44, the parts being then in the relative positions shown in the upper portion of Fig. 12. Thereafter the insulating sheet 23 is moved longitudinally into place behind the switch member, thus closing the slot 44. After that the base 2| with the various parts directly carried thereby is put in place and fastened by means of the eyelets In Figs. 13 and 14 I have shown a construction similar to that shown in Figs. 9 to 12 except that there are two fused switch units which are similar to each other except .that they are of right and left construction. The left hand unit is or may be identical with the unit already described in connection with Figs. '7 to 11, there being a base 2| with various parts mounted thereon and associated therewith as already described.. The right hand unit is similar except as to reversal of arrangement, there being a base 45 similar to the base 2| but reversed. These two bases 2| and 45 may be regarded as together constituting the insulating base structure of the appliance.-

The two handles are connected together by means of a block 46 so that the two switching members are movable in unison and constitute a unitary switch contact means. The enclosing box 41 is similar to the box 25 except that it is wide enough to receive the two units. The box cover 48 has its handle receiving slot 49 at the center, this slot being wide enough to accommodate the combined double handle. u

The construction shown in Figs. 15 to 19 is similar to that shown in Figs. 13 and 14, but diiers as to certain details of construction. The most important difference is that the base structure, instead of consisting of two separate bases 2| and 45, consists of a single unitary base 50. The provision of a single unitary base avoids the necessity for the two metallic 'plates for supporting and guiding the rectilinearly moving switching members. 4

There is provided an enclosing box 5I having a front cover 52. The base is secured to the rear wall of the box by means of'screws at 53, 53, an

insulating sheet 54 preferably being interposed.

The right and left portions of the appliance are similar except for reversal of arrangement, and the description will therefore be confined, in the main, to the portions at the right side. The base 50 is formed with two slots 55, 55 for the two switching members as shown in Fig. 17. The outer wall of each slot is a surface 50'- corresponding to the face I'i of the) base I and to the face 2|a of the base 2|. Rectilinearly movable in each slot 55 is an insulating plate 56. The plate 56 is provided with a notch 51, the walls of which embrace a portion of the base as clearly shown in'Fig. 19, and the plate is thus guided in its rectilinear movement partly by engagement with thel base and partly by engagement with the insulating sheet 54 at the rear.

Two stationary switch contacts 58 and 59 are mounted on the base 50, being respectively located adjacent the two surfaces of the plate 56.

immediately adjacent the surface 50B. The other switch vcontact 59 has a longitudinal extension 59a and alateral extension 59b which extends across or bridges the planes of movement of the corresponding insulating plate 56. At the front of the base there is a further extension 59c which is engaged and held in place on the base by/a screw 63. The extension 59c is provided with a Wire terminal 64 which is positioned close to the before-mentioned face 5|)a of the base.

Carried by the insulating 'plate 56 is a conducting element 65 which extends through a suitable aperture in the said plate. This element is so positioned that upon rectilinear movement of the plate 56 it is moved into or out of a position between the stationary contacts 58 and 59. Fig. 17 shows the element 65 in its closed-circuit position betweenthe contacts, and Fig. 19 shows it in its open-,circuit position out of engagement with the contacts.

As clearly shown in Figs. 17, 18, and 19 the conducting element 65 is held in place in the plate 56 by means of small projecting fins 65, 65EL which are formed by a punching operation after the element has been assembled with the plate.

For manually moving the two plates 56, 56 in unison there is provided a handle member 66 to which both of the plates 56, 56 are connected, as for instance by means of screws 61, 61. This handle member engages the front of the base and serves to assist in guiding the rectilinear movement of the switching members. The handie member 66 has a forward projecting handle` the two switching members can be moved to close or open the circuit as desired.
